SPECIFICATION forming part of Letters Patent No. 597,083, dated January 11, 1898.

Application filed $eptember 11, 1897. Serial No. 651,359. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT XV. MALLO, a citizen of the United States, residing at Leavenworth, in the county of Leavenworth and State of Kansas, have invented certain new and useful Improvements in Fruit-Jars and Covers for the Same, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming a part hereof.

M y invention has relation to improvements in covers for fruit and similar jars; and it consists in the novel construction of parts more fully set forth in the specification and pointed out in the claim.

In the drawing the figure is a verticalmiddle section taken through a jar and having my cover thereon.

The object of my invention is to construct a fruit-jar cover which will be simple in construction, cheap, durable, and positively airtight. In detail it may be described as follows:

Referring to the drawing, 1 represents the body of a glass jar, and 2 the neck thereof. The walls of the neck are made somewhat thicker than those of the body of the jar, the outer surface of the neck being provided with a spirally-screw-threaded surface 3, about which is adapted to be screwed a metallic cap 4, the said cap being of sufficient depth to embrace an inside top or lid 5,which is adapted to rest on an annular ledge 6, located adjacent to the screw-threaded surface of the neck. The ledge 6 is bounded along the inner circle thereof by a vertical wall 7, against which the inner vertical wall 8 of the depending rim 9 of the inside top bears, the base of the rim resting directly on the ledge 6. Formed along the upper surface of the bounding walls of the neck, between the wall 7 and the inner circle of the neck, is an annular groove 10, substantially semicircular in cross-section, a corresponding and registering groove 11 being formed in the adjacent surface of the inside top, the complete groove thus formed being adapted to receive a rubber ring or packing 12, which, after the screw-top 4: has been driven firmly against the inside top 5, serves to make the jar perfectly air-tight.

Having described my invention, what I claim is- A fruit-jar and cover therefor, comprising a body portion, a neck for the same, an outer screw-threaded surface along the outer wall of the neck, a horizontal ledge located adjacent to said screw-threaded surface, a vertical wallbounding the inner circle of the ledge, an annular groove being formed on the upper surface of the neck between the vertical wall referred to and the inner circle of the neck, an inside cover having a peripheral depending rim adapted to rest on the ledge and bear against the vertical wall of the same, an annular groove being formed along the inher surface registering with the groove of the neck, the resulting groove being adapted to receive a suitable packing-ring, and an outer cap or cover adapted to be passed over the inside top and secured to the outer screwthreaded wall of the neck, the depending rim of the inside cover being out of contact with the packing-ring, the latter being wholly con fin ed within the inner and outer circles of the neck, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ALBERT XV. MALLO.
